in one wall of the cell to another perforation 20 in the opposite wall of the cell. The material of theshade is rendered impervious to a part or to most of the suns rays, and the M invention relates to improvements in win ow shades. One of its objects is to provide a light weight shade adapted for use as a window shade or porch shade. Another object is to provide an improved ventilated shade adapted to permit a. circulation of air through the shade and at the same time to exclude strong sunlight. Another obj ect is to provide an improved shade structure adapted to permit a circulation of air through the shade and to temper or modify the character of light permitted to pass through the shade. Another object is to provide an improved shade structure and means of adjusting the shade to different positions. My invention also comprises certain details of form and arrangement, and combination of components, all of which will be fully set forth in the description of the accompanying drawings, '3 in which:

Fig. 1 is a plan of a window shade embodying my improvements.

Fig. 2 is a vertical section taken on line 2 2 of Fig. l.

Fig. 3 is a plan of one of the sections from which the shade is constructed. Y Fig. 4 is a sectional detail of a portion of the shade in its closed or collapsed position.

The accompanying drawings illustrate one l' modification of my invention in which 15 represents a supporting bar, which may be detachably or permanently attached to a porch or to a window frame, and from which the shade is detaohably suspended by means the shade in its lowered position.

" of hooks 16, which are attached rigidly to the In order to Conveniently raise and lower upper cross-bar 17 of the shade and may be the shade, a series of rollers 37, 38, and 39 are hooked over or suspended from the supportmounted and journaled in recesses formed in ing bar 15. The shade is constructed in a the upper cross bar 17, and a horizontal chantubular or cellular form from a series of nel .40 is formed across the top of said cross strips 19 of canvas or other textile material bar 17 .i One shade raising and lowering cord or if desired from a strong parchmentized 41 .is attached at one end to the lower cross type of paper. The strips 19 each have a bar 30, and extends thence upwardly through `series of Ventilating ports 20 cut therein at the center of the cellular structure of the one side of the medial longitudinal line. The shade, and through perforations 42 formed strips 19 are united one to another by means in the respective shade sections 19 until it of a series of lines of stitches 21 and 22, so as reaches the upper cross bar 17 and passes over to form a continuous sheet or shade of a douthe roller 37, thence along the channel to ble thickness of material,having intermediate the roller 39, and thence downwardly over tubular or cellular spaces through which curthe roller 39 to a tassel, or to a point of atrents of air may pass from one perforation tachment on the window frame or porch lation one to another, so that the suns rays will not pass through the perforations 2O in opposite walls of the cells at the same time, thereby providing for a Ventilating current of air through the shade while at the same time intercepting the suns heat and light rays.

At the lower end of the cellular shade structure is a lower cross har 30, which acts portion of the shade, and also as a weight to assist in drawing thev shade down, and in holding it in position. Two spring actuated thrust bars 32 and 33 are preferably mounted in the lower bar 30, with shoes 34 at their outer ends, and with their inner ends turned downwardly, so that when the inner ends 35 are pressed together the shoes 34 are drawn away from and disengaged from the sides of a window frame or porch columns 36 to permit the lower shade cross bar to be raised or lowered. At other times the shoes 34 yieldingly engage the sides of the window frame or thel porch columns 36 to hold the lower cross bar'30 in its yadjusted position and to hold the shade under tension when the shoes 34 and bars 32 and 33 are omitted, the weight of the lower cross bar 30 is relied upon to hold rows of perforations 2O are in staggered reas arigid point of attachment for the lower column. Anothercord 44 is attached at one "end to the loweroross bar 3() and thence eX-V tends upwardly through .another seriesv of perforations l2 through the shade material 19 to the roller38, thence along vthe channel Y 40 t0 ard-lei" wedrthens@upwardly-1t@ a.tassel,.or -to a point of.' attachment upon the Window` framejor a porch column.
